JTree - how to add nodes with a For-Loop?

Question

I have a simple JTree, that systematically adds nodes from relevant vars:

public void init()
{   
    final String section1 = \"JAVA\";

    final S         


        

Answer 1

You could put all of the values into an enum and iterate through that instead.

Answer 2

The solution is very simple:

    for (int i=0; i<sections.length; i++) {
    selection = new DefaultMutableTreeNode(( sections[i]));
    title.insert(selection,0);
    }

sections[i] needs double brackets
